Isolator v7 is Out, and It's Awesome

Let's ignore the visual test coverage, the test autocompletion,
or even the automated test runner that runs your tests in the
background so you instantly know when you write something that breaks a
test. That stuff all rocks and you'll love it.

This is the version that lets you run tests against different versions
of Isolator without having to uninstall/reinstall different versions.
A long-running issue, you've previously always had to build your tests
and run your tests against the exact same version of Isolator. Not a
huge deal if it was a product you could check in alongside your code...
but you have to install it and you can only have one version installed
at a time. No longer! They've finally fixed my #1 complaint and I am
stoked.

Oh, and they added mocking for the filesystem (System.IO.File) and
environment (System.Environment). Nice.
